Hey guys,
I have several ACA500Plus's and today when doing a little Amiga maintenance and updating I realised two of them had not been updated to the latest firmware etc.
I proceeded to flash the latest Menu Update, Install Update and Network Update on the two cards. Both seemed to go through all fine, however when finished, one card was working fine, the other has become "partially bricked".
By partially bricked I mean the card boots to the ACA Menu just fine, but selecting any profile, or hitting F1 or F2 for the two preset profiles causes the system to crash as it is attempting to read the Kickstart ROM.
Sure enough if I hit the TAB key for information in the ACA Menu it says "MAP ROM empty or checksum error".... Okay, somehow the ROM's have been corrupted or deleted, no biggie, I saw a file on the Icomp site for restoring them, so I downloaded the file unarc to a freshly formatted FAT CF card, plugged it into the AUX port, powered on and hit F1..... unfortunately this won't work as F1 reads the stored Kickstart 3.1 ROM..... which is now either corrupted or deleted. Oh.... Okay, what if I set Profile 1 to Mainboard ROM and switch off the MapROM option - this should just boot with the ROM on the A500+ motherboard and I can run the restore files from there.
Well that kinda' works..... except the Mainboard ROM on this A500+ is 1.3 and so the restore image errors out. No probs. I opened the A500+ up and swapped out the KS 1.3 ROM with a KS 3.1 ROM.
Tried again and success! It reads the restore files and flashes both the Kickstart ROMs and the WB disks, then says to remove the CF Card and reboot., which I did.
But the problem is unresolved. It still crashes when attempting to read any ROM that should be in flash memory and ACA information reports the "MAP ROMS empty or checksum error".
Help.
